Crushed Eye Orb

This item detects a particular invasion point in the game in the same way the Black Eye Orb was used exclusively to hunt down Lautrec in Dark Souls.

Once acquired go to Majula and take the path toward the Heide's Tower of Flame. When you approach Licia of Lindelt in the Rotunda, the Crushed Eye Orb will stir. This is an opportunity to fight Licia as a red phantom.

Before this is done, however, make sure that everything is purchased from Licia before this battle starts, because, for one, killing Licia compromises the Gathering of Exiles Achievement/Trophy; also, like any other NPC, killing Licia means that it will no longer be possible to talk or purchase items from her without resurrecting her for 7,000 souls each visit.
